upgrade ..in looking for a cheap memory to my Lenovo X61Tablet, I came across this Komputerbay-Ram. Because I had not heard of the manufacturer, I was skeptical at first, but then to me have decided to order the RAM because the 800MHz Ram 100% compatibility is to certify to 667 MHz modules. Ordered 16:30 Monday, Wednesday-delivered stable cardboard and Ram in double box made of sturdy, rigid film with embossed seal strip. The old memory out and recognized by the 2 Dual Channel bars ersetzt..erster start Bios full 8GB and continue booting into the 64-bit operating system (in this case Ubuntu 11.04) as well as all works smoothly with a much faster speed. To conclude, I also have a memory test run, which I stopped after 1 hour without any errors. Even now in the first hours of operation fältt only the more direct response of the system itself with 30+ tabs in Firefox and tens of applications in the background ..
If everything stays and no unexpected problems under continuous load at even warmer room temperatures (currently 26.7 °) occur, I can Komputerbay 8GB Dual Channel kit with 800 MHz (the 667er mode) fully recommend!
